java - 创建侦听点时出现 Jain SIP 错误

Question

我正在尝试在 Android 中运行 Jain-SIP 示例应用程序，可在此处找到：https ://github.com/usnistgov/jsip/blob/master/src/examples/android/simplecallsetup/Shootist.java

代码尝试在以下行创建侦听点时返回错误

udpListeningPoint = sipStack.createListeningPoint("127.0.0.1", 5060, transport);

代码可以在上面链接的 github 页面上找到。

您知道可能导致错误的原因吗？

github 上给出的 java 示例在 IntelliJ 中运行良好。我为 Jain-SIP 使用以下依赖项：

compile group: 'javax.sip', name: 'android-jain-sip-ri', version: '1.3.0-91'

我正在使用带有 Ubuntu 18.04.2 LTS 的 Android Studio。

我的 MainActivity 类如下

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        new Shootist().init();
    }
}

整个错误输出如下
